Chapter 1 Detail Drive Configuration and Operation
For the block transfer I/O read, the destination tag RIO_700S_BT_I must be an
array of 18 INTs. The tag cannot be DINT. The destination tag will contain the
speed feedback data and data from the Data Out parameters of the drive.
The communication tab of the block transfer I/O read is setup the same as the
block transfer I/O write.
Reference/Feedback Programming
Because the PowerFlex 700S is based on 32-bit and floating-point parameters,
some special data handling is required when using Remote I/O.
To setup the PowerFlex 700S to follow a speed reference from the 20-COMM-R,
parameter 691 [DPI Ref Select] must be set to “Port 5.” Parameter16
[Speed Ref Sel] must be set to “Speed Ref DPI.”
